Allow Aliasing Commodity Symbols

[prikhi]

From @simonmichael:

Some way to alias commodity symbols, since we don't all use the standard ticker symbols.

Maybe for when the config file is done(#6):

commodity-aliases:
  <journal-commodity>: <ticker-symbol>

E.g.,:

commodity-aliases:
  RETIRE: VFFVX

I think following the ledger format for the alias sub-directive for the commodity directive might help in increasing cross-compatibility:

commodity ₹
    alias INR

commodity "INE062A01020"
    alias NSE:SBIN

Could definitely get behind this, to be able to use a fund's ISIN but also have a personal name.

I just went with extending the current yaml config. You can now specify the commodity-aliases option, we will convert to alphavantage symbols when making the api requests & convert back to your journal symbols when writing the price directives.
